Technical Analysis Fundamentals: Structure, Trend and Confirmation

Price structure before indicators

Technical analysis begins with structure: a sequence of higher highs and higher lows defines an uptrend, the inverse defines a downtrend, and overlapping swings define a range. Every indicator ever written is a transformation of the same price series, so structure is the primary evidence and indicators are secondary summaries.

Traders who reverse this order end up with six oscillators disagreeing on a chart whose structure was obvious.

Support and resistance as zones, not lines

Levels where price previously reversed tend to attract activity again because participants remember them and place orders around them. The practical implementation is a zone with width, not a pixel-perfect line. Widening the zone reduces false precision and produces fewer whipsaw exits.

• Prior swing highs and lows.
• Session opens, daily and weekly closes.
• Round psychological numbers.
• Volume-heavy consolidation shelves.

Moving averages: lagging by design

A moving average smooths noise at the cost of delay. That trade-off is the entire tool. A 200-period average identifies regime; a 20-period average identifies short-term momentum. Crossovers are popular because they are easy to code, not because they are predictive; in ranging conditions they generate a steady stream of losing signals.

Momentum, divergence and honest expectations

Oscillators such as RSI or MACD describe the rate of change of price. Divergence — price making a new extreme while momentum does not — is a warning of weakening pressure, not a reversal signal. In strong trends, momentum can remain stretched for weeks while every divergence fails.

Technical analysis is best treated as a framework for organising probabilistic decisions and defining invalidation levels. Combined with the sizing rules from our risk management guide, it becomes a process. Alone, it is a decoration.
